The invention provides a rear side wall structure and a vehicle. The rear side wall structure comprises a D column inner plate, a D column reinforcing plate, a top cover rear cross beam and a top cover outer plate. A first hinge mounting hole is formed in the D-column inner plate, the D-column reinforcing plate is in lap joint with the D-column inner plate and staggered from the first hinge mounting hole, the top cover rear cross beam is in lap joint with the D-column inner plate and the D-column reinforcing plate, and a second hinge mounting hole corresponding to the first hinge mounting hole is formed in the top cover rear cross beam. The top cover outer plate is in lap joint with the D column inner plate, the D column reinforcing plate and the top cover rear cross beam, third hinge mounting holes corresponding to the second hinge mounting holes are formed in the top cover outer plate so that a back door hinge mounting face can be formed at the three-layer lap joint position, and a section does not need to be disconnected between the top cover rear cross beam and the D column reinforcing plate. A continuous lap joint structure is formed between the D column reinforcing plate and the top cover rear cross beam while lap joint of the D column inner plate, the top cover rear cross beam and the top cover outer plate is guaranteed to install a back door hinge, and the Y-direction force transmission effect of the part of an automobile body is improved.

    本公开提供了一种后侧围结构及车辆,后侧围结构包括D柱内板、D柱加强板、顶盖后横梁以及顶盖外板;D柱内板上开设有第一铰链安装孔,D柱加强板搭接在D柱内板上且错开第一铰链安装孔设置,顶盖后横梁搭接在D柱内板和D柱加强板上,顶盖后横梁上开设有与第一铰链安装孔对应的第二铰链安装孔,顶盖外板搭接在D柱内板、D柱加强板以及顶盖后横梁上,顶盖外板上开设有与第二铰链安装孔对应的第三铰链安装孔,以在三层搭接位置形成背门铰链安装面,且顶盖后横梁与D柱加强板之间无需断开一段,保证D柱内板、顶盖后横梁与顶盖外板搭接以安装背门铰链的同时,D柱加强板与顶盖后横梁之间形成连续的搭接结构,提高了此部分车身Y向的传力效果。
